Basal Cell CarcinomaOverviewBasal cell carcinoma (BCC) is the most common type of skin cancer in the United States, affecting more than 800,000 people in the US each year, and occurs more often in individuals with fair skin. A basal cell carcinoma most commonly affects the face or neck, often near the eyelids or the nose. The cancerous cells are believed to arise from the innermost layer of the skin, which is made up of basal cells. The cause of basal cell carcinoma is believed to be exposure to UV radiation in sunlight. Consequently, individuals with greater sun exposure and fair skin are at the greatest risk for basal cell carcinoma. Individuals with dark skin are at a significantly lower risk for developing basal cell carcinoma, simply because they have more melanin (pigment) in their skin, which absorbs greater amounts of UV and reduces its harmful effects on skin cells. But then again, no one is completely immune. Signs & Symptoms of Basal Cell CarcinomaBasal cell carcinoma typically appears as a mass of cells, usually near the eyelid (more commonly the lower eyelid). Often basal cell carcinoma appears as a nodule with a pitted center. In the early stages, a basal cell carcinoma can be deceptively benign, as they can take on the appearance of a simple red patch of skin, or an open sore. One of the classic signs of basal cell carcinoma is that of a sore that doesn't heal. Detection & Diagnosis of Basal Cell CarcinomaAs with all tumors, there is the potential for basal cell carcinoma to metastasize (spread) and affect other tissues in the body. Fortunately, more often than not, cases of basal cell carcinoma are benign and do not spread. Official diagnosis is made by taking a tissue sample of the tumor and examining it under a microscope. Basal Cell Carcinoma TreatmentThere are two options for removal of a basal cell carcinoma: surgical removal or radiation therapy. As with all cancers, early detection is critical, so visit your ophthalmologist or physician if you detect any suspicious growths on or near your eyelids. Prevention of Basal Cell CarcinomaThe best way to prevent basal cell carcinoma is to limit your sun exposure. If this is unavoidable (as is the case for many outdoor workers), ensure that you take all necessary precautions to protect your skin from harmful UV radiation: wear sunscreen (and reapply as recommended!) as well as a hat and sunglasses.
